Awesome!!
For HomeLab pH-meter
Use it as a PH Monitor, works great for me with Display + ESP. Results look stable and correct after initial calibation. I'm using a 25€ (2024) PH probe from Amazon, that people reviewed to be reliable. Used it for ~4 week continously now, no issues so far.
Shipping was fast, Documentation super helpful. Those ESP tools were a bit difficult, but managable (the uploader only runs on older Arduino Versions). Guess for someone dealing with that more frequently it's easy, but I struggled a bit... however, succeeded in the end.
Best thing about it is price-value. Not an engineer, but to me it seems its made well thought through and the isolator allows it to be used with a pump in solution. I was ready to spend 10x more if I get the functionality offered by this modules. Didn't find a suitable consumer priced PH Meter anywhere, only this offered access to data without being forced to use some cloud or whatnot. Thank you very much!
PS. There is one little feature that I was hoping for: It'll be great if the screen could be set to rotate between the different views automatically. Guess that'll also be easier on the OLED.
